Drawing reference numeral explanation
The specific embodiment
As depicted in figs. 1 and 2, be preferred embodiment of the present utility model.
Pin braking during standstill and a release mechanism, be comprised of brake assembly 1, ratchet sheet 2, connecting strap 3, ratchet 4 and pedal assembly 5.
One end of connecting strap 3 and ratchet 4 is hubbed in brake assembly 1 by pivot 15.Between connecting strap 3 and ratchet 4, be provided with the second retracing spring 62, in this embodiment, the second retracing spring 62 is torsion spring, and torsion spring set is on the pivot 15 of connecting strap 3 and ratchet 4 and brake assembly 1, and the two ends of torsion spring are against respectively on connecting strap 3 and ratchet 4.The other end of connecting strap 3 has the guide finger 31 coordinating with track 22.The other end of ratchet 4 has claw 41 and coordinates with ratchet 23, is provided with the 3rd retracing spring 63 between the other end of ratchet 4 and guide pillar 12.
The upper end of pedal assembly 5 and ratchet sheet 2 are fixed together.This embodiment is that cover has axle sleeve 16 on main shaft 13, and the upper end of ratchet sheet 2 and pedal assembly 5 is fastened on axle sleeve 16, and the upper end of pedal assembly 5 and ratchet sheet 2 are fixed together.
When the utility model is used, initial condition as shown in Figure 3, pedal assembly 5 and ratchet sheet 2 perk backward, guide pillar 12 is positioned at the front end of deep-slotted chip breaker 21, guide finger 31 is away from track 22, the claw 41 of ratchet 4 is separated with ratchet 23.
During brake operating, as shown in Figure 4, jam on pedal assembly 5, drive ratchet wheel plate 2 to rotate forward, guide pillar 12 in deep-slotted chip breaker 21 by front sliding backward, guide finger 31 injections 22, as shown in Figure 5, along with continuing to jam on pedal assembly 5, guide finger 31 is along the top of track 22 by front sliding backward, and through the top of track 22, the location concave point to flanging stops sliding guide finger 21, as shown in Figure 6 and Figure 7, now the claw 41 of ratchet 4 just in time coordinates location with ratchet 23, realizes pin braking during standstill.
During unlocking operation, under Fig. 7 state, secondary jams on pedal assembly 5, drive ratchet wheel plate 2 to rotate forward, guide pillar 12 slides into the rear end of deep-slotted chip breaker 21, as shown in Figure 8 again, now the claw 41 of ratchet 4 departs from ratchet 23, guide finger 31 first exits from the location concave point 223 of flanging, then through track 22 below by backward front slide, to guide finger 31 away from track 22, as shown in Figure 3, realize pin parking release.
